CONDENSING APPARATUS.

Original application iiled March 8, 1917, Serial No. 153,454. Dividedand this Serial No. 195,904.

To all 'whom z't man concern.'

Be it known tat I, Roiiiinr SUCZEK, a subject of the Emperor ofAustria-Hungary, residing in the city of Philadelphia, county ofPhiladelphia, and Stute of Pennsylvania, have invented certain new anduseful Improvements in Condensing Ap aratus, of which the following is nspecification.

My invention relates to jet condenser apparatus wherein, as wellunderstood in the art, cooling water comes into direct contact with thesteam or other vapor which is to be condensed.

In such ap aratus it is common to employ n centriiiigal pump forremoving all the liquid, comprising both the injection cooling water andthe condensed vapor or steam, the pump generally being submerged in thewater in the bottom of the apparatus. Such a removal pump removes notonly the water referred to, but also considerable air existent in theinjection water and in part, the air entering the condenser with thesteam. In association with such apparatus it is common also to employ anair pump of any suitable type for removing air or uncondensable gases tomaintain n vacuum higher than would be possible by the einployment ofthe removal pump alone.

It is the object of my invention to cause the removal ump to remove ngreater proportion of t e nir and tuereby reduce the amount of air to beremoved by the nir pump. To this end I provide one or more ducts,conduits or pipes communicating with the Suction inlet of the pro ellerof the ccntrifugal pump and extending into the liquid collecting chamberof the condenser to a point well above the level of the liquid therein.

For an illustration of one of the various forms my invention may take,reference is to be had to the accompanying drawin,

Referring to the drawing, J is the bo` y of the jet condenser whichreceives through the opening E the steam or other'vapor bo be condensed.Surrounding the body .I is the water distributing chamber C receivingthe cooling or injection 'water through the connection W. ln the Wall ofthe body J is formed n series of nozzles or openings .N through whichthe cooling water is in- Specication of Letters Patent.

application lllol October 1l,

jected into contact with the steam entering at E. The steam in contactwith the I6 cooling water is condensed into water, and the in'etionwater und condensate fall throng the cone, guide passage or difusor Dinto the bottom of the body J, when i3 risesto a level maintained abovethe uppeb M most level of the suction of the submcef impeller I of thecentrifugal removal I. The impeller I is driven by tha S rotatin, inbearings B and drifen any suitabyle motor, as n steam turbine op C8electric motor, not shown. The implltl I discharges into the volutedischarge (Ilsing V, which delivers to any suitable point outside of theapparatus.

'ithin the body J are provided the tubes, ducts or nir conduits Textending above the variable liquid level A und communicating at theirupper ends refernbly above the lower end of member ll) with the airspoed within the condenser and at their lower ends being deflectedlaterally at L and deliver ing at K into the suction orifices of and onopposite sides of the impeller I.

*ixtending into the lateral tubes L to a point approximatehtheirorifices K nre the pipes P2 terminating in the nozzles P.

Communicating with the nir space of the condenser is an opening Oconnecting through the pipe Q with an air removing pump G'of any type,as an entrainment pump, iin ejector, or the like.

The operation is as follows:

The im eller I by its rotutioin'iis well understood1 in the art,withdraws water from the bottoni of the bod J and delivers it into thevolute or diedi/arge casing V, from which it is delivered to anysuitable point exterior to the u paratus.

This water has entrained therein air originally entering with theinjection wete! und u some of the air entering the condenser with thesteam to be condensed.

More air may be removed, however, b use of the conduits or tubes T osindica in which case the impeller suction will draw nir from the airspace of the condenser through the tubes T, thereby producing orassisting in producing n vacuum in the c0ndenser, and the air will passinto the impeller I with the water and be removed 105 therewith. By thisaction more air is Iomoved, and there is accordingly less load upon theair removing device connected This application is a division from my aplication Serial Number 153,454, lfiled arch 8, 1917.
